re: "For example, could you buy a HD being marketed for the Macintosh, and

We currently estimate that any random third-party SCSI disk has about a 50%
chance of working with the HP9000 Series 300 boot ROM (rev C or later) and
the HP-UX disk driver (rev 6.0 or later).

If the incompatibility is restricted to software, the answer is yes in any
case.  Since if it doesn't work, you can make it work.  We ship the scsi.c
driver source with HP-UX.  Hack away!

The MAC computers use a 25-pin DB25 (RS-232C style) connector instead of
the standard ALT-2 50-pin, but other than that, I am not certain of how
they vary from ANSI.  I'll ask our SCSI guru to respond.
